No. 531,990 Claims priority, application =Germany, Mar. 4,1965, R 40,039 1 Claim, (Cl. i2-17) ABSTRACT 0F THE DSCLOSURE Acartridge feed for guns comprising a box-like vertical- 1y displaceableconveyer for the cartridge in the riile receiver. The conveyer isactuated by a lever mechanism which moves it upward from a normalposition to a position in front of the ride barrel. The cartridge isguided by the receiver along both its longitudinal sides and at its rearend by a stop plate.

The invention relates to a cartridge feed in magazinefed rifles whichpermits the firing of a plurality of successively arranged cartridges insuccession from a tubular magazine in a gun barrel, using a partcontrolled by a breech block.

According to the invention this is achieved by means of a cartridge feedwhich is characterized by a stop plate and side guide rails for guidingthe cartridges on a vertically displaceable chamber-like magazinecarrier, the forward end of which is disposed in the plane of the rearends of the tubular magazine and the riile bore respectively and thecarrying surface of which, corresponding to the length of the cartridge,is aligned either with the tubular magazine or the rifle bore in such amanner that the rearmost cartridge in the tubular magazine is pressedupon the carrier surface by spring force or is disposed in front of theriile bore in the cartridge chamber, a chamber lock with a pair ofrecesses disposed at different levels, the upper one of which serves tostop the tensioned chamber lock and the lower one to receive the returnimpact and a control part of the carrier actuated by an actuating leverguard.

A further embodiment of the invention comprises a two-arm lever mountedon a pin in the rilie stock, the forward, longer arm of which has alongitudinal slot for a claw provided in the carrier, the rearwardshorter arm being positioned below, under the inuence of a leaf springdisposed in a chamber and arranged on the top of an angular lever with aguide head, said guide head being rotatable abouL a pin mounted in therie stock, a further angular lever with a longitudinal slot being seatedon said bolt, for securing to a linl'L and a lever whose guide pinextends into the longitudinal slot of the angular levers arm.

Particularly advantageous 1s the rounded portion of the release angleelement extending into a corresponding recess, to assure a trouble-freestoppage of the bolt.

Furthermore, the guide rails extend to the level of the rie bore andabut the cartridges in the chamber with clamping action, resulting in ajam-proof transfer of the cartridges and preventing the cartridges fromfalling out.

Finally, the guide tracks are formed with a rounded recess at the levelof the tubular magazine, corresponding to the outer diameter ofthecartridge.

The invention is illustrated, schematically by way of example in thedrawing, in which:

FIG. l is a partial section in the area of a magazine-fed rifle inunlocked condition;

FIG. 2 illustrates the breech of FIG. l, but in loaded condition andFIG. 3 is a cross-section taken on line Ill-III of FIG. l.

the breech of 3,387,398 Patented June 11, 1968 ICC The magazine-fed rideconsists of a gun barrel 1 and a tubular magazine 2 for receivingcartridges 3, which are under spring tension, in known manner. The rearends of the gun barrel and the magazine lie in the same plane. Back ofthese is the breech bolt 4 and receiver 5 and receiver lock 6, which isunder the tension of a pressure spring (not shown) and is provided,forwardly, with a cartridge extractor. A conveyer 7 is disposed in thechamber, the forward end of the conveyer contacting the rear end of thetubular magazine and of the gun barrel, the cartridge bearing surface ofthe conveyer being displaceable vertically of the tubular magazine or ofthe gun barrel, the rear end of the conveyer abutting a stop plate 26and its side cheeks being slidable between clamping guide bars 25. Atthe same time, the length of the conveyer or the distance between thestop plate 25 and the rear side of the gun barrel, corresponds to thelength of the cartridge. The movement of the conveyer is etlected bymeans of a two-armed conveyer lever 8 which is mounted on a pin 9. Thefront lever arm has a longitudinal slit 10 into which extends a pin 11.The lower side of the rear arm is biased by a spring 12 mounted in thechamber 12a and is loaded to hold the conveyer in the position shown inFlG. l.

A release member 13 having a guide head 14 actuates the upper side ofthe rear of conveyer lever arm 8, said angular member being swingablymounted about pin 15 of the riile stock. Another angular lever arm 16 isfurther seated on the pin 15, and is provided with a longitudinal slot17 and a pin 1S for controlling a link 19, which is provided on thepressure pin 20 of the release member 13.

The rifle stock is further provided with a pin 21 for the lever 22, 23,both of which are integral. The lever has a guide pin 24, which extendsinto the longitudinal slot 17 of the angular lever arm 16. When thelever 22 moves into the position shown in FIG. 2, the cartridges on theconveyer 7 are moved by the control parts 8, 13, 16, 19 in front of thegun barrel.

The breech bolt 4 has on its underside a pair of recesses 27 and 2S. Aclaw of the release angle 13 extends into the former whereby thereceiver lock 6 is held in tensioned condition. Should the releasemember 13 be pressed downward by the movement of the lever 22, 23 thereceiver lock 5 is released, whereby the cartridge which is in rear ofthe gun barrel, is moved into the latter. At the same time the L-shapedlever 16 reaches into the second recess 28 and blocks the receiver lock6 in a locked position.

It should be noted that the front lever of conveyer lever 8 is longerthan the rear one and that the recess 27 is deeper to the right than tothe left, when the conveyer 7 with the cartridge 3 thereon is already infront of the gun barrel.

Should the cartridges have been fired, the expended shell remaining inthe riile is expelled by means of a claw from the barrel, the bolt istensioned and stopped and the conveyer 7 moved downward. As it reachesits lowest position, the rearmost cartridge is pushed out of the tubularmagazine and reaches the position shown in FlG. l.

rthe leaf spring 12, tensions the rear arm of the lever S, which pressesthe free end of the release angle 13 and thereby assures the stopping ofthe bolt.
